MP4571GQBE - Synchronous Buck Converter

Download the MP4571GQBE datasheet PDF. This datasheet also covers the MP4571 variant, as both devices belong to the same synchronous buck converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MP4571 is a fully integrated, fixedfrequency, synchronous step-down converter.

It can achieve up to 1A of continuous output current with peak current control for excellent transient response.

Key Features

  • including built-in soft start, enable control, and a power good indicator. High duty cycle and low-dropout mode are provided for automotive cold crank conditions. In addition, the chip provides overcurrent protection with valley current detection, which helps prevent current runaway. It also has hiccup short-circuit protection (SCP), input undervoltage lockout (UVLO), and auto-recovery thermal protection. With internal compensation, the MP4571 offers a very compact solution with a minimum number.

MP4571 High-Efficiency, 1A, 60V, Fully Integrated Synchronous Buck Converter DESCRIPTION The MP4571 is a fully integrated, fixedfrequency, synchronous step-down converter. It can achieve up to 1A of continuous output current with peak current control for excellent transient response. The wide 4.5V to 60V input voltage range accommodates a variety of step-down applications in an automotive input environment. A 2μA shutdown mode quiescent current makes it ideal for battery-powered applications. The MP4571 integrates internal high-side and low-side power MOSFETs for high efficiency without an external Schottky diode, and is available in a 12-pin QFN package.
